Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover incorrect or missing use of supplied validation frameworks during development.

SI-10 Information Input Validation good match

SI-10 directly requires checking validity of inputs, which structurally prevents failure to use or misuse of a validation framework.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented development processes and tools can mandate correct adoption of language or library validation frameworks.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require correct adoption of language-provided or library input-validation frameworks.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect missing validation but does not enforce framework adoption.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates use of approved validation frameworks and libraries.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for proper input validation mechanisms.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles encourage validated input handling but do not prescribe frameworks.

A.8.28 Secure coding partial match
prevents

Secure coding directly requires correct use of language-provided or approved validation libraries.
